Question

我有这个型号：

class EntryBook(models.Model):
    status = models.IntegerField(max_length=2)
    date = models.DateTimeField(auto_now_add=True, blank=True)
    person = models.ForeignKey(Person)
    book = models.ForeignKey(Book, related_name="b_entrybook")
    topiccenter = models.ForeignKey(TopicCenter, related_name="tc_books")

    def __unicode__(self):
        return self.book.title

我试图保存新对象：

tc = TopicCenter.objects.get(id=int(tcid))
user = request.user.get_profile()
book = Book.objects.get(id=int(request.POST.get('bookid')))
newbookentry = EntryBook(status=1, person=user, book=book, topiccenter=tc)
newbookentry.save()

我收到错误消息：

TypeError: 'person' is an invalid keyword argument for this function

鉴于person是模型的正确属性，为什么它是无效的关键字参数？

Answer 1

newbookentry = EntryBook(status=1, person=user, book=book, topiccenter=tc)

应该是：

newbookentry = EntryBook.objects.create(status=1, person=user, book=book,
    topiccenter=tc)

TypeError：'person'是此函数的无效关键字参数
